I tend to feel more anxious than usual during PMS times. And I usually have a day when I feel more depressed. I notice this more now that I haven't been on the pill since having my daughter 4 years ago (I was on the pill for like 12 years). On the plus side, I don't get the migraines I used to get while on the pill. Hormones can definitely affect our emotions--it's a big part of why postpartum depression (which I had, too) is a thing.
